Client Side Caching

I've downloading WAPT for evalution and so far I am really impressed. The only problem I have that is preventing me from purchasing is that I can't seem to get WAPT to implement client side caching.

I've testing my spplication using Firefox/Firebug and verified that client side caching is enabled. Once cached my pages are usually no larger than 20k. In WAPT I have removed the param - no cache, but still my 10 minute test run of 10 users is averaging 191k per page so it appears not to be implementing the client side caching.

I have tried another performance tester and it seems to cache ok, but I like WAPT overall better, so hopefully I can get this sorted out. I need to be able enable the client side caching so I can accurately test our WAN bandwidth for capacity.
